Dagger build error

Question

I've got two objects which I inject with dagger2 without any problems. When I add third one (the same way like two before), project does not rebuild and gives errors, that points into first two (nothing here about added third one):

error: com.google.firebase.database.DatabaseReference cannot be provided without an @Inject constructor or from an @Provides- or @Produces-annotated method.
com.google.firebase.database.DatabaseReference is injected at
com.hotmail.at.jablonskimichal.dni.wolne.od.handlu.ui.splash.SplashPresenter.freeDaysCloudReference
com.hotmail.at.jablonskimichal.dni.wolne.od.handlu.ui.splash.SplashPresenter is injected at
com.hotmail.at.jablonskimichal.dni.wolne.od.handlu.providers.components.MainPresenterComponent.inject(destination)

Every three modules and components are implemented in the same way. Of course when I delete added third one, projects compiles easily.

Module which messes project build:

@Module
public class MainPresenterModule {

    private final MainPresenter presenter;

    public MainPresenterModule(MainPresenter presenter) {
        this.presenter = presenter;
    }

    @Singleton
    @Provides
    MainPresenter provideMainPresenter() {
        return presenter;
    }

}

Component:

@Singleton
@Component(modules = {MainPresenterModule.class})
public interface MainPresenterComponent {
    void inject(SplashPresenter destination);
}

Maybe useful: I am using those libraries for DI with dagger2:

    implementation 'com.google.dagger:dagger-android:2.11'
    implementation 'com.google.dagger:dagger-android-support:2.11'
    annotationProcessor 'com.google.dagger:dagger-android-processor:2.11'
    annotationProcessor 'com.google.dagger:dagger-compiler:2.11'

with newest android studio (3.1.1) and gradle (3.1.1) on mac osx. Of course I've tried invalidating cache and restarts, cleans etc. I've checked imports and all of them are the same.

Edit: When I remove usage of injection

    @Inject
    DatabaseReference shopsCloudReference;

    public MainPresenter(MainController controller) {
        super(controller);
        Core.injectShopsComponent().into(this);
    }

And

    @Inject
    DatabaseReference freeDaysCloudReference;

    public SplashPresenter(SplashController controller) {
        super(controller);
        Core.injectFreeDaysComponent().into(this);
    }

project compiles, but it is not what I wanted.

EDIT There's lot of answers that I didn't add firebase libs in gradle. My full gradle:

why does it say firebase in the error? are you using firebase? it doesn't show in your dependencies... — Levi Moreira, Apr 20 '18 at 14:43
I use two firebase database objects and It works well until adding third DI object which is `MainPresenter.class`. Every of them I implement in the same way. — Michał Jabłoński, Apr 20 '18 at 14:51
Please have a look at [How to fix cannot be provided](https://stackoverflow.com/q/44912080/1837367) for more information, You don't provide `DatabaseReference` anywhere, so Dagger can't inject it. — David Medenjak, Apr 20 '18 at 17:25

Well, you wrote :

@Component(modules = {MainPresenterComponent.class})

It should be :

@Component(modules = {MainPresenterModule.class})

Ohh.. I've seen this before, but copied wrong text. Error concern to proper class. I've edited question. Sorry – Michał Jabłoński Apr 20 '18 at 14:40
As @Levi_Albuquerque pointed out, you are trying to inject `DatabaseReference` but it is not appearing in your dependencies – Omar Aflak Apr 20 '18 at 14:51
It does, but I didn't mentioned about it. – Michał Jabłoński Apr 20 '18 at 14:58

You probably should "mention about it", considering it is important for answering the question. – EpicPandaForce Apr 20 '18 at 20:35
